Product Description:

The MHD115C-058-NG0-LN belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. It is a servo motor used in automated axes that demand high continuous torque and closed-loop feedback. In factory cells, the unit converts drive commands into rotary motion for conveyors, packaging equipment, and machining stations. This operating role makes it suitable for applications that require repeatable motion control and stable response under changing loads.

The motor supplies 70.0 Nm of continuous standstill torque, providing solid holding capability when an axis remains under load. Heat is removed by liquid cooling, which helps the motor maintain output while keeping surface temperatures under control. A digital servo feedback (HSF) encoder returns fine position data to the drive for accurate control of speed and shaft angle. The housing meets IP65, helping keep out dust and water jets in typical industrial environments. The motor is supplied without a holding brake, so vertical axes require an external holding method when power is removed. Rated operation covers 0 to 40 °C, which suits normal indoor production areas. Insulation Class F supports elevated winding temperatures, the left-side power connector can simplify cable routing, and the plain shaft is intended for clamp-style or friction-fit couplings. Winding code 058 sets the electrical characteristics for this motor, while the C length variant keeps the housing compact within the 115 frame size.

Position accuracy reaches ± 0.5 angular minutes, supporting synchronized motion and precise interpolation between multiple axes. Mechanical alignment is supported by a 180 mm centering diameter and a 192 mm square flange that match common gearbox and machine mounting surfaces. A shaft seal helps protect the bearings when oil, coolant, or debris reaches the output end. The motor can be stored from -20 °C to 80 °C, allowing it to withstand typical warehouse conditions before installation. Installation is permitted at elevations up to 1000 m above sea level without derating, which supports use in standard industrial locations.
